jakarta.faces.convert.NumberConverter.setType validation causes a TCK failure

Link to the Javadoc: https://jakarta.ee/specifications/faces/4.0/apidocs/jakarta/faces/convert/numberconverter#setType(java.lang.String)

The TCK sets an invalid type and MyFaces throws the following exception causing the TCK test to fail:

Caused by: jakarta.faces.FacesException: Uknown type: integer
    at jakarta.faces.convert.NumberConverter.setType(NumberConverter.java:579)

The Javadoc only says the following:

"Set the number type to be used when formatting and parsing numbers. Valid values are currency, number, or percent. An invalid value will cause a ConverterException when getAsObject() or getAsString() is called. " 

The additional validation that MyFaces is doing is not compliant with the specification and needs to be removed.
